Body and Mind; Sex and Stress photoHave you ever wondered that the role of testosterone in enhancing libido and enhancing erections in men cannot be its only role? There are many other roles and biological effects of testosterone other than its known presence in bodily fluids. It has been blamed for excess hair loss (medical name-Androgenetic alopecia) although the molecular steps of hair loss in men and women are not fully understood.

This hormone is secreted in the testes of males and the ovaries of females, although men produce more of it. Various kinds of mental behavior are not only subject to influence by environment and genetics but also day-to-day hormonal changes. For example, stress can also inhibit testosterone synthesis and hence lead to decreased levels of it secretion.

Some goods news has recently emerged. Recent studies have shown that to keep stress at bay you should frequently engage in penetrative penal-vaginal sex. Unfortunately many people from all walks of life find that under stress, they do not have the desire to have sex and even creates undesirable side effects such as sexual dysfunction.

A brilliant study (Biological Psychology, volume 71, page 214) showed that sex but more preferably intercourse is much more effective in combating stress then other sexual activity such as masturbation. As intercourse is more linked with less blood pressure and less stress this cause’s better psychological and physiological function. Also orgasms for women during penile-vaginal intercourse are better for physiological behavior but not so much for orgasm during other sexual activities. As some of us are nervous about speaking in public or stage fright as its commonly called are being recommended to have sex (not on the stage of course) for the stress calming effect.

It is thought when a couple makes love the neurotransmitter oxytocin released relaxes the body and decreases blood pressure hence also preventing stress. Oxytocin is secreted by the brain and other organs including the ovaries and testes. It is believed that oxytocin is significantly decreased during the stress and infusion of the hormone relieves stress in animal models thereby suggesting a role in regulating some physiological responses to stress.

In the light of such elegant studies and lack of public stress programmes such as screening by government agencies aimed at improving recognition, treatment, and reducing stress and depression primary prevention has become necessary. As stress and depression has become a common disorder with serious many unwanted side effects both in men and women, penetrative penal-vaginal sex could be a primary stress prevention strategy.

Vitamin A was first discovered back in 1912, by a Polish biochemist named Casimir Funk. He came up with the word vitamine, which was later given the name vitamin. Funk was the first to discover vitamins as we know them today, although vitamin A was actually the first one discovered, hence the letter “A” in the title of the vitamin.

You can find vitamin A in natural foods such as oranges and yellow fruits. It can also be found in vegetables as well, such as spinach and fats. When found in vegetables, vitamin A is water soluble, coming in the form of beta carotene. The beta carotene form of vitamin A can be eliminated from your body through natural processes, making it an excellent way to get vitamin A.

Vitamin A is required by the body on an every day basis to maintain healthy skin and keep your eyesight on track. There are many people who say that carrots provide enough vitamin A to prevent you from getting night blindness. The fact is, ancient Egyptian doctors prescribed liver in their time, which they said contained enough vitamin A to combat night blindness. Vitamin A is also known as an antioxidant, which makes it ideal to prevent cancer and anti aging. Along with these benefits, it also helps with your immune system as well.

To get the proper absorption of vitamin A, you’ll need to consume fat. Those of you who happen to be on a low fat or restricted diet, simply may not be getting the right amounts of vitamin A from your supplements that you may think. To get the proper absorption of vitamin A in your diet, you’ll need to consume a high enough level of protein. Protein combines with vitamin A to make it stronger, and help it move through your body.

On a normal day, you should be consuming around 5,000 international units (IU) of vitamin A. Depending on your health and your age, you may need to consume more or less. The safest form of vitamin A is beta carotene as mentioned above, and it can be taken in much larger doses. No matter what age you may be, you can feel safe to consume high amounts of vitamin A in the form of beta carotene.

If you don’t consume enough vitamin A in your diet, you’ll end up with a deficiency. A deficiency is never a good thing, as it normally results in skin problems, increased infections, and even night blindness as well. A prolonged deficiency in vitamin A can put you at a risk for cancer as well, and you’ll also miss out on any effects of anti aging that the vitamin might have. Although you should begin taking it immediately if you have a deficiency, the effects wouldn’t be the same as they would be if you stayed up to date with the right amount on a daily basis.

On the other hand, if you are getting too much vitamin A, you’ll put yourself at risk for pain in your joints, abdomen, and your bones. Even though too much or not enough can cause you serious side effects, you should always get the right amount in your diet. Vitamin A is very important, and should always be included in your diet. You can find it in many foods, or take supplements that include the well needed vitamin.
